Is that the only exchange that token is listed on, if yes then the team are not really ready to work neither are they ready to grow the price of their token as they claimed. What you should know is that, the project team can never talk down or say something bad about their project, they will always look for a way to encourage users as well as convince them they are working and token price will pump, but most of the times, team that do such hardly keep to their promises. On the other hand, most project team pays more attention on their products and services, looking for more ways to make it attractive because they know, that is what is capable of making their token valuable.
However in my own opinion, before investing in such token and following what the team are saying, do invest with what you can afford to lose, because yobit is not really a good exchange, in fact it's been a long time I heard about anything about it.
